YRDDK250JR

The Yurdusar YRDDK250JR is the largest and most demanding model in the documented ECO JR power harrow series, with a working width of 250 cm, intended for farms with the most powerful tractors and largest cultivated areas. Like the other models in the series, it is driven by the tractor's PTO shaft, and uses fixed-type vertical tines that work the soil vertically to a depth of 20 cm, without inverting it, preserving soil moisture. A toothed rear roller prepares an even seedbed, creating an ideal environment for seed germination and increasing crop yield. Overall machine dimensions are 260 x 112 x 130 cm, the largest in the series, in line with the maximum working width. The rotor is fitted with 20 blades, the most in the whole series, distributed to cover the 250 cm working width while preserving working quality across the full width. Machine weight is 881 kg, the highest in the series, reflecting the largest rotor, widest working width and most robust frame construction. Operation requires a tractor of 75 to 85 HP, the highest range in the series, in line with the greatest mass and working width. The YRDDK250JR is intended for large farms needing maximum working width per pass for efficient seedbed preparation across large areas, while retaining the benefits of the economical, simple construction of the whole ECO JR series. Although the most demanding model in the series by weight and required tractor power, the working principle remains the same as the smallest model - a fixed vertical tine without soil inversion, with a toothed rear roller for final leveling and breaking up of the seedbed.
